<p>The future and success of GraphicsMagick depends on your contributions.
By contributing to GraphicsMagick you will benefit from the
features/fixes you contribute, can take pride in taking part in the
development of a quality product, and you can tell your friends that you
contribute to the GraphicsMagick project.</p>
<p>There are a number of ways you can contribute:</p>
<ul class="simple">
<li><p>Submit bug reports to the GraphicsMagick bug tracking system at
SourceForge.</p></li>
<li><p>Submit patches to the GraphicsMagick patch submission system at
SourceForge.</p></li>
<li><p>Perform test builds on unusual systems and report the results.</p></li>
<li><p>Submit ideas and proposed designs to the graphicsmagick-core
mailing list.</p></li>
<li><p>Create a new language interface, dependent library, or application.</p></li>
<li><p>Join the GraphicsMagick Group as a full-fledged developer with
Mercurial commit access.</p></li>
<li><p>Develop new 'convert6' and 'mogrify6' front ends which emulate
essential option parsing features of ImageMagick 6.X while
supporting operations currently in GraphicsMagick.</p></li>
</ul>
<p>Regardless of how you choose to contribute, your contributions will be
treated with the respect and value that they deserve.</p>
<p>Becoming a member of the GraphicsMagick Group requires a majority vote
from existing members. Your chances of being admitted to the group are
increased significantly if you have a proven track-record of success
on other open source projects, are a recognized expert in the field,
or have already demonstrated your capabilities and commitment by
contributing to the project in other ways. Please contact Bob
Friesenhahn &lt;<a class="reference external" href="mailto:bobjfriesenhahn&#37;&#52;&#48;gmail&#46;com">bobjfriesenhahn<span>&#64;</span>gmail<span>&#46;</span>com</a>&gt; in order to be considered for
group membership.</p>
<section id="areas-to-contribute">
<h1>Areas To Contribute</h1>
<p>The following are areas where significant contributions may be made to
the GraphicsMagick project:</p>
<ul class="simple">
<li><p>Create a language interface using SWIG &lt;<a class="reference external" href="http://www.swig.org/">http://www.swig.org/</a>&gt; to
support scripting in Perl, Python, TCL/TK, Guile, MzScheme, Ruby,
Java, PHP, and CHICKEN, based on a common implementation.</p></li>
<li><p>Create a new utility command parser based on a separate LALR or
XML-based syntax definition, and using an approach suitable to
replace the existing error-prone command parsers in magick/command.c</p></li>
<li><p>Create a vector encoder for EPS, Postscript, PDF, SVG
&lt;<a class="reference external" href="http://www.w3.org/Graphics/SVG/">http://www.w3.org/Graphics/SVG/</a>&gt;, WebCGM
&lt;<a class="reference external" href="http://www.w3.org/Graphics/WebCGM/">http://www.w3.org/Graphics/WebCGM/</a>&gt;, or WMF.</p></li>
<li><p>Create an OpenEXR coder based on the OpenEXR
&lt;<a class="reference external" href="http://www.openexr.com/">http://www.openexr.com/</a>&gt; library from Industrial Light &amp; Magic.</p></li>
<li><p>Create a <em>pstoedit</em> module to import Postscript, EPS, and PDF
files as vector data using pstoedit &lt;<a class="reference external" href="http://www.pstoedit.net/">http://www.pstoedit.net/</a>&gt; which
already includes a high-quality driver to render Postscript vectors via
GraphicsMagick. This module could also export vector data in many
formats using pstoedit's output drivers.</p></li>
<li><p>Add integrated Adobe XMP
&lt;<a class="reference external" href="http://www.adobe.com/products/xmp/index.html">http://www.adobe.com/products/xmp/index.html</a>&gt; profile support for
TIFF, JPEG, PNG, PDF, EPS, and Postscript.</p></li>
<li><p>Port Erik Reinhard's super-cool Parameter Estimation For
Photographic Tone Reproduction
&lt;<a class="reference external" href="http://www.cs.ucf.edu/~reinhard/Reinhard02/">http://www.cs.ucf.edu/~reinhard/Reinhard02/</a>&gt; algorithm to
GraphicsMagick.</p></li>
<li><p>Create portable GUI which can work under Microsoft Windows, OS-X,
X11, and Wayland (via a portable widget toolkit), to replace the
outdated X11 GUI implmentation.</p></li>
<li><p>Create an interface between GraphicsMagick and OpenOffice.org.
&lt;<a class="reference external" href="http://www.openoffice.org/">http://www.openoffice.org/</a>&gt; so that OpenOffice may load and save
any format supported by GraphicsMagick. OpenOffice.org offers a
separate SDK so there may be a number of other opportunities to
explore.</p></li>
